16. Abstract
Due to the increasing use of deicing chemicals and the subsequent intrusion of chlorides into bridge decks, it is
necessary to expand the use of available protective measures, including waterproofing materials. Waterproofing
options that fall into three categories; 1) membranes (liquid and sheet systems), 2) friction polymers (laminates), and
3) polymer asphalts. This study assessed the waterproofing characteristics of these products. Prior to this study, no
common test had been established to compare the performance of waterproofing products. A test method was
developed that closely follows ASTM D5084, “Standard Test Methods for Measurement of Hydraulic Conductivity
of Saturated Porous Materials Using a Flexible Wall Permeameter,” for this purpose. This test provided valid
information to compare performance of waterproofing options.

KTC Research Report Waterproofing Options for Bridge Decks ii
Executive Summary
The Kentucky Transportation Cabinet (KYTC) initiated the study KYSPR 17-531,
“Waterproofing Options for Bridge Decks,” to identify application, performance, testing, and other
technical aspects of waterproofing products available for bridge decks.
The study included a review of waterproofing products that were categorized into four groups: 1)
liquid membranes, 2) sheet membranes, 3) friction polymers (laminates), and 4) polymer asphalts.
Various products from each category were reviewed and identified for potential testing.
Manufacturer’s data was also reviewed for each product in an effort to identify any common
waterproofing test method. This review was inconclusive. Kentucky Transportation Center (KTC)
researchers decided, in response, that it would be necessary to develop a single waterproofing test
method to compare waterproofing characteristics of the various products available. This method
will allow comparison of performance of the various products available.
Existing literature contained little information on conducting permeability testing over a broad
range of products. Studies were reviewed where tests have been performed on asphalt and high-
performance concrete using triaxial cells at pressures as low as 4.3 psi(1) to more than 3,600 psi(3).
A study on pressures applied by heavy trucks indicated pressures between 90 to 130 psi(2).
KTC’s development of permeability testing began with the use of a constant head permeameter at
a head pressure of 30 psi. This pressure could have been higher to expedite testing, however, some
of the products tested were as thin as 0.07” and susceptible to swelling or possible damage. Testing
closely followed ASTM D5084, “Standard Test Methods for Measurement of Hydraulic
Conductivity of Saturated Porous Materials Using a Flexible Wall Permeameter.”
This study focused predominantly on waterproofing capabilities. The test method developed is a
good comparative test, however, the method should be further refined for it to be considered for
use in material qualification. There are other characteristics to be considered when choosing a
waterproofing product as well.

1. Introduction
The increased use of deicing chemicals (especially liquid treatments) necessitate the installation
of bridge deck surfacing measures that waterproof the decks, improving their resistance of chloride
ion penetration. A variety of options are available with varying degrees of effectiveness, cost, and
longevity. Surfacing/waterproofing options include: waterproofing membranes (liquid and
sheeting systems), polymer asphalts, and friction polymers (laminates). Some of these products
can be maintained over the life of a bridge with periodic renewal of the wearing surface. Others
can be replaced easily with minimal impact to the travelling public. Some can be applied by state
forces, while others must be applied by contractors using specialized equipment. These options
need to be investigated to create a Kentucky Transportation Cabinet (KYTC) toolkit of options for
treating and maintaining bridge decks.

2. Objectives
This research had four objectives:
1. Identify surfacing/waterproofing options, including information about their application,
performance, testing, and other technical aspects.
2. Determine laboratory performance testing methods for prequalifying waterproofing materials
for experimental and routine use by KYTC. Employ those to identify candidate waterproofing
systems.
3. Propose waterproofing options (types and specific products) that can be adopted by KYTC for
use in new construction and maintenance.
4. Provide necessary support for KYTC to employ candidate systems on an experimental basis
(special note preparation).
To achieve those goals, KTC researchers addressed the following tasks:
1. Identify waterproofing methods and specific products, including application requirements,
costs, and performance using a literature search and contacts with manufacturers and select
departments of transportation (DOTs).
2. Determine/perform applicable laboratory and field tests to evaluate the effectiveness of the
waterproofing methods. Employ those tests to evaluate candidate waterproofing products.
3. Develop necessary documentation for KYTC to employ bridge deck waterproofing materials
with acceptable performance on an experimental basis (QPLs, special notes).
4. Prepare a final report documenting the research.

3. Research Approach
This study focused primarily on the waterproofing characteristics of products offered to protect
bridge decks from water intrusion. The products currently used for waterproofing fit into four basic
categories: 1) liquid membranes, 2) sheet membranes, 3) thin overlays (laminates), and 4) thick
impermeable overlays. With respect to permeability testing, our review of manufacturers’ product
data sheets revealed little commonality in testing that could be used for comparative proposes. A
few manufacturers claim products to be waterproof or impermeable without documented test data.
Of the products with documented data, the test methods/standards varied, including tests for
permeability, absorption, and vapor transmission. (Table 1). All of these tests are conducted at low
or no hydraulic pressure. There are insufficient similarities in the documented tests to adequately
compare their performance. A literature search was performed focusing on waterproofing
characteristics and permeability testing.
A report published in 2009(1) studied the effect of traffic-induced moisture based on the Average
Daily Traffic (ADT), speed, loading, and tire pressure. Permeability testing was performed in the
field and Time Domain Reflectometry (TDR) probes were installed beneath pavement to measure
the moisture content of the soil. Laboratory testing was limited to determining the moisture content
of soil samples collected during placement of the TDR probes. Asphalt was tested in the field using
two methods: 1) falling head permeameter with an initial pressure of 30 kPa (4.35 psi) and 2) a
constant head permeameter at a pressure of 30 kPa (4.35 psi). Results showed permeability varied
between 1.07x10-3 to 5.85x10-3 cm/s.
The pressure applied by heavy truck traffic varies significantly due to several factors, including
loading, tire size, tread design, inflation, and contact area. Assuming typical loading of 4,250
pounds per tire, contact pressure can vary from approximately 90 to 130 psi (2).
Another study published in 1995(3) focused on the development of high pressure triaxial testing of
high-performance concrete. The goal was to develop a test method with reproducible results when
testing permeability values range between 10-10 to 10-14 cm/s. Testing was performed with constant
head pressure and confining pressure of approximately 6.5 MPa (943 psi) and 24.5 MPa (3,684
psi), respectively. These extreme pressures were used to expedite testing.
The New York State Department of Transportation (NYSDOT) has used waterproof hot mix
asphalt (HMA) to overlay concrete bridge decks (4). ASTM D5084, “Standard Test Method for
Measurement of Hydraulic Conductivity of Saturated Porous Materials Using a Flexible Wall
Permeameter,” (Method A) was used to verify waterproofing performance. Head and cell pressures
of approximately 70 and 100 psi were used, respectively. To limit side wall seepage, Vaseline was
applied to the sides of specimens. NYSDOT specifications require that waterproof HMA
permeability test results be less than 1x10-5 cm/s. The result of the tests performed was 5.24x10-7
cm/s.
Based on the diversity among the manufacturer’s test standards and test methods found in the
literature search, this study’s objectives were amended to develop a permeability test to adequately
compare test results of the various products available. These changes are described in the
amendments below.

4. Product Acquisition
Product submissions were solicited from several manufacturers/suppliers. Products were classified
into four categories: 1) sheet membranes, 2) liquid membranes, 3) laminates/thin overlays, and 4)
polymer asphalt or concrete. The intent was to acquire two products in each category. This proved
successful with the exception of the thick overlay category. Only one product falling within this
category was submitted.
All participating vendors were asked to submit three specimens of their product applied on
16”x8”x4” concrete cap blocks. This substrate was chosen because it has a higher rate of
permeability compared to typical concrete. One submission could not be applied in the requested
manner. It was not practical for polymer asphalt to be prepared in the requested manner. Part of
Contract ID 174301 in KYTC District 5 entailed replacing plug joints on Interstate 65 bridges
between MP 131.3 and 135.4 with polymer asphalt. Kentucky Transportation Center (KTC)
personnel extracted cores from an approved test patch in the paving company parking lot (Figure
1). Table 2 lists product type and composition submitted for testing.
KTC Research Report Waterproofing Options for Bridge Decks 6
5. Laboratory Tests
Permeability (Specimen Preparation):
Using a 4” core drill (Figure 2), nine cores were extracted from untreated concrete cap blocks.
These cores were used to begin development of the testing method and establish that the coefficient
of permeability was higher than that expected of the waterproofing material. For each product
submitted, six cores were extracted from two of the treated blocks. Three of these cores were used
to further develop the method. Once the method was finalized, initial permeability data were
recorded. The remaining cores were held for testing at a later date in an attempt to determine
repeatability of the tests.
To facilitate the de-airing process, cores were cut to leave approximately 0.50” of concrete cap
block material below the waterproofing material (Figure 3). Each polymer asphalt core was cut to
a consistent thickness of 1.5”. To remove contaminants introduced during the coring and cutting
process, all cores were rinsed thoroughly with deionized water after each process. They were then
submerged in deionized water to aid in saturation.
Absorption (Specimen Preparation):
Three cores were extracted for absorption testing and rinsed as previously described. These
specimens were prepared in accordance with ASTM D6489, “Standard Test Method for
Determining the Water Absorption of Hardened Concrete Treated with a Water Repellant
Coating.” Three cores from each product were oven dried at 75°C (167°F). A specimen was
considered oven dry when a weight change of ≤ 0.2% was observed in a 2-hour period. Once an
oven-dry weight was achieved, specimens were cooled to room temperature and weighed
(recorded as WA). The outer edges of each core were coated with paraffin that had been melted at
60°C (140°F). Care was exercised to ensure the treated surface was not contaminated. This sealing
process was repeated twice to assure no leakage during testing.
Development of Permeability Testing:
The literature review indicated the use of testing pressures as low as 4.3 psi to in excess of 3,600
psi. Tire pressures of 90 to 130 psi from heavy trucks are cyclical, which could not be reproduced
in the lab given the project’s scope. A modified version of ASTM D5084, “Standard Test Method
for Measurement of Hydraulic Conductivity of Saturated Porous Materials Using a Flexible Wall
Permeameter,” (Method A) with a constant head pressure of 30 psi was used to test all specimens.
Three 4” concrete cap blocks were purchased from Home Depot, and three 4” cores were cut from
each. Initially these nine cores were tested in a permeameter (Figure 4) without vacuum capability.
The porosity of the material allowed evacuation of air in a reasonable time. Permeability of the
nine cores ranged from 2.58(10-4) to 2.74(10-4) cm3/sec. The cores treated with the waterproofing
material could not be de-aired in this permeameter, so a different cell with the capacity to apply a
vacuum to the base and cap assembly was used (Figure 5). This setup consisted of the permeameter
with vacuum and water to the cap and base, a pressurized head water reservoir (approximately 1
gallon), and a reservoir used as a water trap for the applied vacuum. See Figure 6 for a diagram of
the hydraulic circuit. The same nine cores were retested in this cell and results ranged between
1.80(10-4) to 1.87(10-4) cm3/sec.
KTC Research Report Waterproofing Options for Bridge Decks 7
The de-airing process on cores that had been treated with waterproofing material proved to be time
consuming. Once de-airing was complete and testing began, permeability measurements were very
unstable. Water seepage between the edges of the specimens and the confining membrane was
determined to be the cause of the instability. Numerous measures were taken to address this issue,
including varying head and confining pressures. Using a head pressure of 30 psi and cell pressure
of 60 psi, along with a very thin coating of high-vacuum grease applied to the outer edges of the
specimens, resolved the seepage issue. To reduce the time needed for de-airing, each specimen
was cut approximately 0.5” below the waterproofing material. The samples of polymer asphalt
were tested at a thickness of 1.5”. All specimens were submerged in deionized water for a
minimum of 24 hours prior to testing.
The testing procedure began with the application of a vacuum at 20 in. Hg to both the cap and base
for approximately one hour. Cell and head pressures were gradually increased to 60 psi and 30 psi,
respectively, until no air was observed in the discharge. Once no air was observed, the vacuum
was removed and only head pressure remained on the cap. The outflow of water was directed
through a length of 1/8” tubing that had been taped along the work surface. The volume of the
tubing was 0.02141 cm3 per cm of length. The flow was timed and measured in 15-minute intervals
until the flow stabilized per ASTM D5084 Paragraph 9.5.4.1. Once stabilized, four measurements
were recorded and used to calculate permeability. When testing material with a coefficient of
permeability greater than 1x10-7 cm3/sec the output was collected in a breaker and weighed. Tables
3–9 present the results.
The following equation was used for calculating permeability:
𝑘 =𝑞𝐿
𝐴ℎ
Where: k = Coefficient of permeability
q = Discharge in cm3/sec
L = Length of specimen in cm
A = Cross-sectional area of specimen in cm2
h = Constant head causing flow in cm
Absorption Testing (ASTM 6489):
Absorption testing was performed to determine if absorption performance correlated with the
results of permeability testing. Three prepared specimens were weighed and recorded as W1. They
were then placed face down on glass rods (.125” diameter) in a dish. Deionized water was added
to the dish to a depth of 1.5” from the top of the glass rods (Figure 7). Each specimen was removed
after 24 hours, wiped with a damp cloth, and weighed. They were then re-submerged in water for
another 24 hours and weighed again. Each weight was recorded as W2. Tables 10 and 11 contain
the results.
The percent absorption for each 24-hour period was determined as follows:
𝑃𝑒𝑟𝑐𝑒𝑛𝑡 𝐴𝑏𝑠𝑜𝑟𝑝𝑡𝑖𝑜𝑛 =100𝑥(𝑊2 − 𝑊1)
𝑊𝑎
Where: W1 = oven dry weight
KTC Research Report Waterproofing Options for Bridge Decks 8
W2 = sealed weight
Wa = 24 or 48 hour weight
KTC Research Report Waterproofing Options for Bridge Decks 9
6. Conclusions
This study focused on the waterproofing characteristics of bridge deck treatments designed to
prevent the ingress of water and chlorides into the underlying concrete. These characteristics are
of primary concern when selecting a waterproofing product, however, other properties should be
considered as well, including tensile properties, bond strength, abrasion resistance, hardness,
puncture resistance, chemical resistance, compressive strength, crack bridging, skid resistance,
freeze thaw resistance, and thermal expansion characteristics.
The test methods documented by manufacturers of waterproofing treatments are almost as varied
as the available material. All waterproofing tests are performed at very low pressure. Previous field
testing for chloride intrusion performed by KTC (FRT 194 Experimental Deck Sealants and Pier
Cap Coating on Interstate 471) indicated higher chloride ion levels in the wheel paths than on the
shoulders. Traffic can induce pressures of up to 130 psi on the wheel path. The cyclical action
from traffic continually pumps water laced with chlorides into the deck.
The test described in this study was performed on seven different waterproofing products from six
manufacturers. Results were reasonably consistent, and the test was repeatable. Thus, it proved to
be a valid comparative test. Further refinement of the method is necessary if the test is to be
considered for use in product qualification.
KTC Research Report Waterproofing Options for Bridge Decks 10
7. Recommendations
Development of this test method should be continued as part of an expanded test protocol to qualify
waterproofing material for inclusion in the KYTC Approved Product List. Training should be
developed and implemented to assure competency and accuracy of testing. Pilot projects should
be implemented and monitored.
